The United States Geological Survey (USGS) upgraded the magnitude of Saturday’s earthquake in Pawnee County from a 5.6 to a 5.8 on the Richter Scale.
The earthquake struck at 7:02 a.m. on Sep. 3, eight miles northwest of the town of Pawnee at a depth of about four miles.
The USGS initially rated the quake as a 5.6, but now say, after further analysis of seismic recordings. The quake damaged buildings in Pawnee and on the campus of Oklahoma State University in Stillwater. Some buildings in SE OKC also sustained damage.
In addition to upgrading the Pawnee earthquake, the USGS also retroactively upgraded the November 2011 Prague earthquake from a 5.6 to a 5.7.
